Expense Tracker (JavaFX)

A small JavaFX desktop tool: add expenses (date, category, amount, note), see them in a sortable table, delete entries, and watch a running total update live. Data is saved to expenses.csv next to the jar, so it persists between runs - no database required for a tool this size.

This is the template for the "Standard" tier of the Java desktop tool gig (multi-screen JavaFX app with save/load) - swap the domain (expenses -> inventory, clients, bookings, whatever the client needs tracked) and the same structure holds.

Project structure

java-desktop-utility/
├── pom.xml
└── src/main/java/com/tjchaplain/expensetracker/
    ├── Main.java            # JavaFX UI + application entry point
    ├── Expense.java         # data model
    └── ExpenseStore.java    # CSV load/save

Run it

mvn javafx:run

(Requires JavaFX on the classpath - the pom.xml already pulls in javafx-controls via Maven, so mvn javafx:run handles it automatically.)

Packaging as a standalone executable

For the Premium tier (packaged as a runnable executable), use jpackage (bundled with the JDK) or the javafx-maven-plugin's jlink/jpackage goals to produce a native .exe/.app a client can double-click with no Java or Maven installed.
